I guess it's a bit different because you are not this guys girlfriend, he never asked you to be and doesn't seem attached to you. But he seems super jealous too, and it appears there are more complicated issues at play. I think it is better to tell him it's over between you two, whatever it was you had than just fade away, but I understand why you think the latter will be easier.
I would just like to add that if someone does really care about you, 'fading away' can be the most heartbreaking and devastating thing for them, especially if you are in a relationship with them. It is dragging out the pain and making them question their self worth. I think it is the WORST way to break up with someone who has treated you well, if he hasn't though I think you don't really owe him much of anything.
